Hi
I am preparing wireless network topology.
I want to add Antnet agent to mobile nodes so that output gives routing
table for each node as per Antnet Algorithm.
Here is the code given bellow.
can anybody help me??
set val(chan) Channel/WirelessChannel ;#channel type
set val(prop) Propagation/TwoRayGround;#radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
set val(mac) Mac/802_11 ;#MAC type
set val(ifq) Queue/DropTail/PriQueue ;#interface queue type
set val(ll) LL ;#link layer type
set val(ant) Antenna/OmniAntenna ;#antenna model
set val(ifqlen) 50 ;#max packet in ifq
set val(nn) 2 ;#number of mobilenodes
set val(rp) AODV ;#routing protocol
set val(x) 500 ;#X dimension of the topography
set val(y) 500 ;#Y dimension of the topography
#Define options:adhoc-routing protocol,network stack,channel,etc.
#create simulator
set ns [new Simulator]
set tracefd [open example2.tr w]
$ns trace-all $tracefd
set namtracefd [open example2.nam w]
$ns namtrace-all-wireless $namtracefd $val(x) $val(y)
#ns trace and nam trace are opened,all tracing is
#enabled, annotates the nam trace with information
#about the size of the topography(its x and y
#dimensions)
proc finish {} {
global ns tracefd namtracefd
$ns flush-trace
close $tracefd
close $namtracefd
exec nam example2.nam &
exit 0
}
#create a finish function. the traces are flushed
#to disk before the simulator is halted,ns trace
#and nam trace are closed
set topo [new Topography]
$topo load_flatgrid $val(x) $val(y)
#set up topography object. Create a flat topology in a x m * y m area
create-god $val(nn)
# Create a God(General Operations Director) Object
#A God object must be created.It annotates trace logs with
#information about the optimal number of hops from a source to a
destination,used for statistics and routing
#protocol evaluations.
$ns node-config -adhocRouting $val(rp)\
-llType $val(ll)\
-macType $val(mac)\
-ifqType $val(ifq)\
-ifqLen $val(ifqlen)\

#Define how a mobile node is configured
for {set i 0} {$i < $val(nn) } {incr i} {
set node_($i) [$ns node]
$node_($i) random-motion 0
}
for {set i 0} {$i < $val(nn)} {incr i} {
set node_($i) [new Agent/Antnet $i]
}
#Use “for” loop to create two nodes attach it to the channel disable
random motion

$node_(1) set X_ 390.0
$node_(1) set Y_ 385.0
$node_(1) set Z_ 0.0
$ns at 50.0 "$node_(1) setdest 25.0 20.0 15.0"
$ns at 10.0 "$node_(0) setdest 20.0 18.0 15.0"
$ns at 100.0 "$node_(1) setdest 490.0 480.0 15.0"
#Node position defined in a 3-D model
#However z axis not used to create Node movement
set tcp [new Agent/TCP]
$tcp set class_ 2
set sink [new Agent/TCPSink]
$ns attach-agent $node_(0) $tcp
$ns attach-agent $node_(1) $sink
$ns connect $tcp $sink
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ns at 10.0 "$ftp start“
#creating a TCP connection from node_(0) to node_(1),setup
# a FTP traffic flow at time 10.0
for {set i 0} {$i < $val(nn)} {incr i} {
$ns at 150.0 "$node_($i) reset";
}
#Print routing tables generated by AntNet
for {set i 0} {$i < $nn} {incr i} {
$ns at 12.0 "$node_($i) print_rtable"
}
# Tell nodes when the simulation ends
$ns at 150.0 "finish"
#run the finish function at 150.0
$ns run ;# Start simulation
